| 1 | Ultrasonically activated scalpel versus monopolar electrocautery shovel in laparoscopic total mesorectal excision for rectal cancer显示文摘AIM: To investigate the feasibility and safety of monopolar electrocautery shovel (ES) in laparoscopic total mesorectal excision (TME) with anal sphincter preservation for rectal cancer in order to reduce the cost of the laparoscopic operation, and to compare ES with the ultrasonically activated scalpel (US). METHODS: Forty patients with rectal cancer, who underwent laparoscopic TME with anal sphincter preservation from June 2005 to June 2007, were randomly divided into ultrasonic scalpel group and monopolar ES group, prospectively. White blood cells (WBC) were measured before and after operation, operative time, blood loss, pelvic volume of drainage, time of anal exhaust, visual analogue scales (VAS) and surgery-related complications were recorded. RESULTS: All the operations were successful; no one was converted to open procedure. No significant differences were observed in terms of preoperative and postoperative d 1 and d 3 WBC counts (P = 0.493, P = 0.375, P = 0.559), operation time (P = 0.235), blood loss (P = 0.296), anal exhaust time (P = 0.431), pelvicdrainage volume and VAS in postoperative d 1 (P = 0.431, P = 0.426) and d 3 (P = 0.844, P = 0.617) between ES group and US group. The occurrence of surgery-related complications such as anastomotic leakage and wound infection was the same in the two groups. CONCLUSION: ES is a safe and feasible tool as same as US used in laparoscopic TME with anal sphincter preservation for rectal cancer on the basis of the skillful laparoscopic technique and the complete understanding of laparoscopic pelvic anatomy. Application of ES can not only reduce the operation costs but also benef it the popularization of laparoscopic operation for rectal cancer patients. | Bao-Jun Zhou, Wei-Qing Song, Qing-Hui Yan, Jian-Hui Cai, Feng-An Wang, Jin Liu, Guo-Jian Zhang, Guo-Qiang Duan, Zhan-Xue Zhang, Department of Gastrointestinal Surgery, The Second Hospital of Hebei Medical University, Shijiazhuang 050000, Hebei Province, China Author contributions: Zhou BJ, Song WQ, Yan QH, Cai JH, Wang FA, Liu J, Zhang GJ, Duan GQ and Zhang ZX contributed equally to this work Zhou BJ, Song WQ, Yan QH, Cai JH and Wang FA designed the research Zhou BJ, Liu J and Zhang GJ performed the research Duan GQ and Zhang ZX analyzed the data and Zhou BJ, Song WQ and Yan QH wrote the paper. | 2008 | World Journal of Gastroenterology2008，14，25： | 25 |
| 2 | The compression of IR spectra by using wavelet neural network显示文摘IR spectra play an important role in determining the structure of compounds qualitatively andquantitatively.In general a great number of data are required to exactly show the features ofthe compounds.Regarding various compounds,there are massive IR spectra.With the basicfeatures of IR spectra being reserved,it is important to compress IR spectra for improving thestorage,index and process of IR spectra.The wavelet neural network(WNN)is a newneural network model based on wavelet analysis.However,its introduction and applica-tion in chemistry have not been reported.In this note,WNN is applied to the compression ofthe IR spectra of polystyrene.The results show that the original spectra can be | Liu, W Li, JP Xiong, JH Pan, ZX Zhang, MS | 1997 | Chinese Science Bulletin1997，42，10： | 8 |
| 3 | Pulmonary infection control window in treatment of severe respiratory failure of chronic obstructive pulmonary diseases: a prospective, randomized controlled, multi-centred study显示文摘Background Early withdraw from invasive mechanical ventilation (MV) followed by noninvasive MV is a new strategy for changing modes of treatment. This study was conducted to estimate the feasibility and the efficacy of early extubation and sequential noninvasive MV commenced at beginning of pulmonary infection control window in patients with exacerbated hypercapnic respiratory failure caused by chronic obstructive pulmonary diseases (COPD). Methods A prospective, randomized controlled study was conducted in eleven teaching hospitals' respiratory or medical intensive care units in China. Ninety intubated COPD patients with severe hypercapnic respiratory failure triggered by pulmonary infection (pneumonia or purulent bronchitis) were involved in the study. When the pulmonary infection had been controlled by antibiotics and comprehensive therapy, the 'pulmonary infection control window (PIC window)' has been reached. Each case was randomly assigned to study group (extubation and noninvasive MV via facial mask immediately) or control group (invasive MV was received continuously after PIC window by using conventional weaning technique).Results Study group (n=47) and control group (n=43) had similar clinical characteristics initially and at the time of PIC window. Compared with control group, study group had shorter duration of invasive MV [(6.4±4.4) days vs (11.3±6.2) days, P=0.000], lower rate of ventilator associated pneumonia (VAP) (3/47 vs 12/43, P=0.014), fewer days in ICU [(12±8) days vs (16±11) days, P=0.047] and lower hospital mortality (1/47 vs 7/43, P=0.025).Conclusions In COPD patients requiring intubation and invasive MV for hypercapnic respiratory failure, which is exacerbated by pulmonary infection, early extubation followed by noninvasive MV initiated at the start of PIC window may decrease significantly the duration of invasive MV, the risk of VAP and hospital mortality. | Wang, C Zhan, QY Cao, ZX Wei, LQ Cheng, ZZ Liu, S Zhang, JL Chen, RC Luo, Q Niu, SF Zhu, L Wu, DW Fang, BM Wu, TH Wang, CZ Liu, YN | 2005 | Chinese Medical Journal2005，，19： | 6 |
